Regarding the food section, Elena did not rush to explain.

There are some things, no matter how many words describe them, they are not as intuitive as they have been seen and experienced once.

Therefore, after briefly instructing the lunch process for today's lunch, Elena accompanied the Lovegood family on a tour of the campus, as Dumbledore had instructed—of course, by Xenophilius?? Lovegood leads the way.

In the UK, almost all adult wizards graduated from Hogwarts.

For most wizards, Hogwarts is a second home in life, full of fond memories.

Therefore, even after bidding farewell to school for more than ten years and returning to Hogwarts Castle again, Xenophilius?? Lovegood still remembers the passages of the castle and the way to get there.

"This is the staircase that leads to Ravenclawa, where your mother and I are from. ”

Standing by the gate at the top of a long, curved staircase, Xenophilius?? Lovegood gently stroked the eagle-shaped bronze knocker that was exactly the same as in his memory, and continued with nostalgia.

"Ravenclaw is the smartest and most open college, and we don't have anything to hide. No matter who it is, when you knock on the door, the Eagle Ring will ask you questions, and if you can answer correctly, you will be allowed to enter. ”

"What if you get it wrong?" asked Luna, curious.

It was not uncommon for a dozen people to stand at the door of the common room and try to answer the day's questions. But then you can at least learn something, and that's Ravenclaw, understand?"

Xenophilius?? Lovegood shrugged his shoulders, his eyes filled with memories of his old days on campus.

"But don't worry, it's all very simple, at least your mother and I have never been stopped outside the common room. ”

"Well, I see. Luna said earnestly, a hint of excitement on her face, "It's a bit like the guessing puzzles we usually play, right, Daddy? Hogwarts is such a fun place." ”

"That's right, let's see who can answer Eagle Ring's question faster?"

Xenophilius?? Lovegood nodded happily, looked at Luna and said softly - as for a certain silver-haired little wizard standing behind the two of them, he directly ignored it, after all, Hufflepuff House has always been good at using his brain.

There is no doubt that the common room of Ravenclaw is Xenophilius?? Lovegood's first choice, as an "eagle", can find his way back to Ravenclaw at Hogwarts Castle even with his eyes closed.

The only thing that made him a little concerned was, for some reason, a row of light blue velvet sleeping bags hanging from the wall of the hallway below the staircase, each of which seemed to have a small note with its name on it.

Hmm, is there a new way for the kids at Ravenclaw Academy?

Xenophilius?? Lovegood shook his head in confusion, withdrew his gaze, and raised his hand to knock lightly on the old, sleek wooden door in front of him, just as he had been in school a dozen years ago.

The hawk's beak opened at once, but instead of making a bird's call, it said in a gentle, musical voice:

"There were a certain number of three-headed dogs and phoenixes in one room at the same time, forty-six heads from above, and seventy feet from below. How many three-headed dogs and how many phoenixes are there in the room?"

“？？？”

Xenophilius?? The expression on Lovegood's face froze, and he blinked slightly comically.

What kind of strange problem is this?

In his impression, this type of topic seemed to be the first time he had seen it.

Well, while the Eagle Ring has always been a quirky question, it is common for the Eagle Ring to ask more poetic questions, such as "Where did the disappeared thing go", "Which one came first, the phoenix or the fire", "What material should be used to stir the stirring rod when brewing an unknown potion of strong corrosion", ......

And for some reason, the question always gave Xenophilius a nasty feeling full of malice.

Xenophilius?? Lovegood seemed to vaguely understand the meaning of the existence of those light blue sleeping bags in the corridor downstairs, and it was really not easy for these little Ravenclaw wizards now.

Faced with the suddenly unfamiliar Eagle Ring, Xenophilius?? Lovegood frowned, and began to try to imagine the scene described by the Eagle Ring.

"Head and feet, well, a big room with a phoenix and a three-headed dog......"

"Phoenix, three-headed dog, forty-six ......"

At the same time, Luna whispered Eagle Ring's question as she crossed her fingers and began to think seriously.

Before Lovegood's father and daughter could sort out their thoughts, Elena's voice came from the two of them.

"Thirteen phoenixes and eleven three-headed dogs. ”

"Correct. The eagle ring said softly, and the wooden door swirled and opened back.

Since it was class time, the Ravenclaw common room was empty, and the entire college dormitory environment was filled with an ethereal atmosphere, with elegant arched windows open on the walls and blue and bronze silks.

The ceiling is domed with stars painted on it, and the dark blue carpet below is also covered with stars. There were desks, chairs, bookshelves, and a white marble statue of Lady Ravenclaw in an alcove opposite the door.

Next to the statue is a door, Xenophilius?? Lovegood knew it was the passage to the dormitory at the top of the tower.

However, he wasn't in the mood to continue introducing the common room of Ravenclaw College.

Like all Ravenclaws, their curiosity about the unknown and new knowledge is far more than everything - even if Elena says the correct answer, he still does not understand the "knowledge" of the question itself, which is undoubtedly quite a bad feeling.

"Why? I mean, it's just an answer, right......"

Xenophilius?? Lovegood turned his head to look at Elena, who was standing behind the two, "If you may, can you tell us how you came to this question so quickly?"

"It's simple, because I came up with this question. ”

Elena shrugged her shoulders and explained softly with a calm face, "There are many detailed solutions, and if I have time, I may open a separate section in 'Singing Contradiction' to explain some of the problems in this regard." As for now, because time may not be a more appropriate occasion. Because ......"

After a slight pause, Elena glanced thoughtfully at the bronze eagle ring in front of her.

Thinking about it, the simple number problem is still a bit too boring, and as time goes by, it is not conducive to the school experience of the little Ravenclaw wizards, maybe she should find a way to help Eagle Ring enrich the question bank.

"By the way, Mr. Lovegood, I have an interesting idea, would you be interested in hearing it?"

Elena glanced at Xenophilius, whose face was full of intellectual curiosity?? Lovegood, the corners of his mouth slightly raised.

She suddenly realized a problem, and wanted to attack the Lovegood family, and the question bank update work of the Bronze Eagle Ring was undoubtedly the easiest thing for them to have a sense of accomplishment and interest.

In fact, many math problems can actually be translated into more interesting stories.

For example, once upon a time there was a barber......
